Direct Inward Dialing (DID)

A cloud phone system offers business users a wide range of business phone features, including many advanced features that businesses with POTS (plain old telephone service) lines cannot access!

These types of phone numbers are often referred to as “Direct Inward Dialing” (DIDs) (and multiple DIDs are also classified as DIDs).

Direct inward dialling is a very valuable tool for any business that wants to save time, cost and money. In colloquial terms, it gives the caller the ability to place a call directly to another party without using an operator or operator assistance.

What is Direct inward dialling?

Direct Inward Dialing (DID) occurs when a telephone service provider connects a block of telephone numbers to your company’s Private Branch Exchange (PBX).

Virtual numbers allow businesses to set up extensions that bypass the main reception line and go directly to a particular desk extension. Using DID, you can use local numbers, premium-rate numbers, or toll-free numbers.

For a customer or client, a direct-dial number appears to be just like any other telephone number. However, DIDs are virtual numbers that go directly to an extension or branch in an organisation. You can think of it as a telephone shortcut.

An entity’s direct-dial phone numbers direct inbound calls to its phone system. This direct number is managed by the VoIP phone system, as it relays calls to an individual user. The VoIP phone system is also responsible for managing the dedicated call routing.

DID trunks are used for this service, which routes the last three to five digits of the phone number to the PBX or router/gateway.

A DID also allows for a custom phone number. For example, you’ll be able to have an area code of 604, and then any combination of numbers following it, such as 604-976-6457.

Features of Direct Inward Dialing and how it affects your business

There are numerous features that are available with a DID such as Automatic Call Distribution (ACD), Caller ID and Auto Attendant/Voice Mail. Voice Over Internet Protocol (VoIP) is the technology that has allowed features like a direct inward dial.

Other additional features include:

  • DID Trunk Queuing with Delay Announcement or Music on Queue
  • DID Two-way Call Transfer
  • Call Planner.

DID trunk queuing is an arrangement whereby incoming calls that are placed to station lines within a DID system can be held in queue if all trunks between the Central Office (CO) switch and your end-users PBX are busy.

Calls in the queue will be held in their order of arrival until a trunk becomes available. Calls in the queue are served on a first-in, first-out basis. Calls in the queue will hear ringing until answered.

Benefits Of Using DID For Your Business

There are times where you may want a prospect to skip the phone menu or receptionist and go directly to your sales department. What about separating where your enterprise versus small business customers are directed?

If you have specific lines for customer service, sales, and other departments, chances are you could benefit from DID – especially when paired with a feature-rich VoIP system.
